*jlinker-start-timeout*

This variable was added in a patch release in late July, 2013. That
patch upgraded jlinker to version
7.1. See jlinker.htm for more information on the
patch and version 7.1.

This variable specifies the default value of the timeout argument
to jlinker-init when
the mode is :start-java. In
the :start-java case, a small timeout value is
appropriate since Java is expected to connect to Lisp almost
immediately.

It may be appropriate to increase this value if a long delay is expected when Lisp
starts another OS process. A smaller value will allow Lisp to respond sooner
to a failure in starting the Java VM.
